Just allocate the two string objects directly. The previously used
new StringBuilder(0).toString() returns the same object for both END
and DELIM when run on Java 15, which breaks the wire protocol since
then END and DELIM cannot be distinguished anymore.

DirCacheEditor unconditionally applied a PathEdit to all stages in the
index. This gives wrong results if one wants to check out a file from
some commit to resolve a conflict: JGit would update the working tree
file multiple times (once per stage), and set all stages to point to
the checked-out blob.
C git replaces the stages by the entry for the checked-out file.
To support this, add a DirCacheEntry.setStage() method so that
CheckoutCommand can force the stage to zero. In DirCacheEditor, keep
only the zero stage if the PathEdit re-set the stage.

Due to Java bug JDK-8220793 [1] Java cannot set timestamps of a symlink
but only of the symlink target. This bug was fixed in Java 13. Since we
don't have a use case to set the timestamp of the symlink itself simply
document the current behavior of setLastModified methods.

PerformanceLogContext threw NullPointerException when multiple threads
tried to add an event to the PerformanceLogContext. The cause for this
is that the ThreadLocal was initialized only in the class constructor
for the first thread; for subsequent threads it was null.
To fix this initialize eventRecords for each thread.

This reverts commit f802f06e7fd5a98f256b7b7727598491f563bf2f.
I had misunderstood how protocol V2 works. This implementation only
works if the negotiation during fetch is done in one round.
Fixing this is substantial work in BasePackFetchConnection. Basically
I think I'd have to change back negotiate to the V0 version, and have
a doFetch() that does
if protocol V2
doFetchV2()
else
doFetchV0()
with doFetchV0 the old code, and doFetchV2 completely new.
Plus there would need to be a HTTP test case requiring several
negotiation rounds.
This is a couple of days work at least, and I don't know when I will
have the time to revisit this. So although the rest of the code is
fine I prefer to back this out completely and not leave a only half
working implementation in the code for an indeterminate time.

Make all transports request protocol V2 when fetching. Depending on
the transport, set the GIT_PROTOCOL environment variable (file and
ssh), pass the Git-Protocol header (http), or set the hidden
"\0version=2\0" (git anon). We'll fall back to V0 if the server
doesn't reply with a version 2 answer.
A user can control which protocol the client requests via the git
config protocol.version; if not set, JGit requests protocol V2 for
fetching. Pushing always uses protocol V0 still.
In the API, there is only a new Transport.openFetch() version that
takes a collection of RefSpecs plus additional patterns to construct
the Ref prefixes for the "ls-refs" command in protocol V2. If none
are given, the server will still advertise all refs, even in protocol
V2.
BasePackConnection.readAdvertisedRefs() handles falling back to
protocol V0. It newly returns true if V0 was used and the advertised
refs were read, and false if V2 is used and an explicit "ls-refs" is
needed. (This can't be done transparently inside readAdvertisedRefs()
because a "stateless RPC" transport like TransportHttp may need to
open a new connection for writing.)
BasePackFetchConnection implements the changes needed for the protocol
V2 "fetch" command (simplified ACK handling, delimiters, section
headers).
In TransportHttp, change readSmartHeaders() to also recognize the
"version 2" packet line as a valid smart server indication.
Adapt tests, and run all the HTTP tests not only with both HTTP
connection factories (JDK and Apache HttpClient) but also with both
protocol V0 and V2. Do the same for the SSH transport tests.

SubmoduleWalk#getModuleName returned the module path instead of the
module name. In order to fix this SubmoduleWalk#getModuleName needs to

Add new performance logging to register events of type duration.
The proposed logging is similar to the performance logging
in OS Gerrit https://gerrit-review.googlesource.com/c/gerrit/+/225628:
a global Singleton (LoggingContext in Gerrit) is
collecting the performance logs in a thread-safe events list,
and at the end of the monitored command the list of events is
retrieved and written to a log, after which it is cleared.
What this patch does:
The main component is the Singleton (PerformanceLogContext), which
is used to collect the records (PerformanceLogRecord) in one place
(ThreadLocal eventsList) from anywhere using
PerformanceLogContext.getInstance().addEvent().
Reason why this change is needed:
The current monitoring in JGit has several issues:
1. git fetch and git push events are handled separately
(PackStatistics and ReceivedPackStatistics), with no unified way
of writing or reading the statistics.
2. PostUploadHook is only invoked on the event of sending the
pack, which means that the PackStatistics is not available for
the fetch requests that did not end with sending the pack
(negotiation requests).
3. The way the logs are created is different from the performance
log approach, so the long-running operations need to be collected
from both performance log (for JGit DFS overridden operations and
Gerrit operations) and gitlog (for JGit ones).
The proposed performance logging is going to solve the above
mentioned issues: it collects all of the performance logs in one
place, thus accounting for the commands that do not result in
sending a pack. The logs are compatible with the ones on Gerrit.
Moreover, the Singleton is accessible anywhere in the call stack,
which proved to be successful in other projects like Dapper
(https://research.google/pubs/pub36356/).

Reason why this change is needed:
Currently the durations of fetch events are computed by
registering time instants with System.currentTimeMillis()
and calculating the differences with simple minus operation,
but multiple sources suggest that the best practice is to use
the Java 8 Duration and Instant objects.
What this patch does:
Get time measurements with Instant.now() instead of
System.currentTimeMillis() and calculate the duration of fetch
events (Reachability checks and Negotiation) using
Duration.between().toMillis().

This enables EGit to override with a lenient variant that logs the
problem and continues with the default value. EGit needs this because
otherwise a corrupt core.excludesFile entry can render the whole UI
unusable (until the git config is fixed) because any use of the
WorkingTreeIterator will throw an InvalidPathException.
This is not a problem on OS X, where all characters are allowed in
file names. But on Windows some characters are forbidden... see bug
567296. The message of the InvalidPathException is not helpful since
it doesn't point to the origin of the problem. EGit can log a much
better message indicating the offending config file and entry in the
Eclipse error log, where the user can see it.

When comparing git directory paths to check whether one is a prefix
of another, one must add a slash to avoid false prefix matches when
one directory name is a prefix of another. The path "audio" is not
a prefix of the path "audio-new", but would be a prefix of a path
"audio/new".

Add a constant for the config; rewrite the whole connection initiation

tests for a single hop and two different ways to configure a two-hop
chain.
The connection timeout applies to each hop in the chain individually.

Since there is no negotiation for a push, the client is probably sending
